YOLUTA ambigiia* 

 TAB. CCCXClX.^Fig. 1. 



Spec Char. Ovato-elongated, acute, costated, 

 transversely sulcated , cost® angular, 

 above ; spire rough ; columella with three 

 plaits ; lip plaited within, its edge granu- 

 lated, aperture narrow above, 

 Syn. S trombus ambiguus, Brander 69. 

 Rather longer shaped than the young of V Luctator 

 in consequence of the narrowness of the aperture at the 

 upper part ; the spire is made rough by a row of small 

 imperfect spines upon the upper edges of the whorls 

 and the angles upon the tops ot the costae. 



A distinct and easily recognized shell, although very 

 likethelast. It aboundsintheCliffat Barton. Branders 

 most excellent figure is from a younger individual than 

 the one purpoself chosen for the present table, and has 

 consequently the'parts sharper defined. It ^^ «;t «"': 

 ficiently clear that Lamarck's V. bicorona is the same 

 species ; I have never met with the true V. ambigua horn 

 France. 



VOLUTA nodosa. 

 TAB. CCCXCIX.— >:^. 2. 



Spec Char. Ovate pointed, obscurely cos- 

 tated, transversely sulcated ; spire with two 

 rows of nodiform spines; columella with 

 three folds ; lip striated withm. 

 The very blunt short spines, deep and numerous sulci, 

 and oval form at once distinguish this Volute 



Discovered above a twelvemonth ago by Miss Be- 

 minster in the Barton CliiV; the specimen figured enrich- 

 es The cabinet of the Rev. T. Cooke ; one sent by Miss 

 Beminster is not quite so ventricose ; in its yo;"^S «tate 

 the knobs are more conspicuous, particularly the row ot 

 smaller ones upon the edges of the whorls.
